Tongue scraping for treating halitosis

Tongue scrapers or cleaners are slightly more effective than toothbrushes as a means of controlling halitosis in adults. This review, which included 2 trials (40 participants) found that, although the use of tongue scrapers was generally well accepted, the effects of tongue cleaning using scrapers or brushes appeared to be very short lived and there was some limited evidence of tongue trauma which occurred with prolonged use of one tongue scraper.
